Making the ‘human-body internet’ more effective

Experiment setup to understand how characteristics of human body communication can be improved. Credit: Dairoku Muramatsu & Yoshifumi Nishida, Source: Equivalent Circuit Model Viewed from Receiver Side in Human Body Communication Wireless technologies such as Wi-Fi and Bluetooth have made remote connectivity easier, and as electronics become smaller and faster, the adoption of “wearables” has increased. From smart watches to implantables, such devices interact with the human body in ways that are very different from those of a computer. However,…

Interplay between mitochondria and nucleus may have implications for new treatment — ScienceDaily

Mitochondria, the ‘batteries’ that produce our energy, interact with the cell’s nucleus in subtle ways previously unseen in humans, according to research published today in the journal Science. The study, led by scientists at the University of Cambridge, suggests that matching mitochondrial DNA to nuclear DNA could be important when selecting potential donors for the recently-approved mitochondrial donation treatment, in order to prevent potential health problems later in life. Almost all of the DNA that makes up the human genome…

Engineering’s Nguyen turns success into Gold(water)

Julie Nguyen is one of just 496 students nationwide to earn a prestigious scholarship from the Barry Goldwater Scholarship and Excellence in Education Foundation. The research bug bit junior Julie Nguyen early. She gave lab work a whirl her freshman year to see if it was for her, and the Chesterfield native has worked in Biomedical, Biological and Chemical Engineering Assistant Professor Bret Ulery’s lab ever since. As it turns out, she’s a wiz both in the lab and on…

Mizzou senior’s NSF Graduate Fellowship a dream achieved

Sarah Gebken reached her goal when the NSF GRFP announced its 2019 recipients recently, locking in annual $34,000 stipends and $12,000 for tuition and fees each year for three years. She’ll head to Washington University in St. Louis in the fall for the next step in her evolution as an engineer. As a freshman, Mizzou Engineering undergraduate Sarah Gebken set a lofty goal — earn a spot National Science Foundation Graduate Research Fellowship Program her senior year. The NSF GRFP…

Data-sampling method makes ‘sketches’ of unwieldy biological datasets while still capturing the full diversity of cell types — ScienceDaily

Artistic sketches can be used to capture details of a scene in a simpler image. MIT researchers are now bringing that concept to computational biology, with a novel method that extracts comprehensive samples — called “sketches” — of massive cell datasets that are easier to analyze for biological and medical studies. Recent years have seen an explosion in profiling single cells from a diverse range of human tissue and organs — such as a neurons, muscles, and immune cells —…

Which car crashes cause traumatic brain injury? New tool to calculate likelihood of traumatic brain injury after a vehicle collision — ScienceDaily

Motor vehicle crashes are the most common cause of emergency room visits, hospitalizations and deaths related to traumatic brain injury among people aged 15 to 34, according to a 2013 report by the Centers for Disease Control and Prevention. Traumatic brain injury, or TBI, makes up about 30 percent of all injury deaths in the United States, and early diagnosis and treatment is one of the most important ways to prevent these deaths. Aerospace and mechanical engineering professor Samy Missoum,…

The Army Ants FIRST Robotics team has been busy collecting awards and accolades at competitions, and they’ll try to claim the biggest of all next month. The team recently qualified for the FIRST Championship in April in Houston by finishing in the semifinals of the Rocket City Regional in…

Researchers engineer a protein micelle that can be visualized by MRI as it delivers hemotherapeutics — ScienceDaily

A team of researchers from New York University has engineered nanoscale protein micelles capable of both delivering chemotherapeutic drugs and of being tracked by magnetic resonance imaging (MRI). The innovation falls into the category of “theranostics,” meaning that it combines diagnostic capability and drug delivery, allowing researchers to administer therapy while also non-invasively monitoring the therapeutic progress and drastically reducing the need for surgical intervention. The team is led by NYU Tandon School of Engineering Professor of Chemical and Biomolecular…

Blood flow restriction therapy may protect against bone loss following ACL reconstruction — ScienceDaily

Anterior Cruciate Ligament (ACL) reconstruction patients often face bone and muscle loss immediately following the procedure. Researchers presenting their work today at the AOSSM/AANA Specialty Day note that combining blood flow restriction (BFR) therapy with traditional rehabilitation efforts may slow bone loss and reduce return to function time. “Providing BFR as part of the rehabilitation efforts following ACL surgery, appears to help preserve the bone, recover muscle loss and improve function quicker, according to our research,” said lead author, Bradley…

Horseshoe crabs are really relatives of spiders, scorpions — ScienceDaily

Blue-blooded and armored with 10 spindly legs, horseshoe crabs have perhaps always seemed a bit out of place. First thought to be closely related to crabs, lobsters and other crustaceans, in 1881 evolutionary biologist E. Ray Lankester placed them solidly in a group more similar to spiders and scorpions. Horseshoe crabs have since been thought to be ancestors of the arachnids, but molecular sequence data have always been sparse enough to cast doubt. University of Wisconsin-Madison evolutionary biologists Jesús Ballesteros…
